PFO 3D Programmable Focusing Optics

FARMINGTON, Conn., Jan. 4, 2013 — Trumpf Inc. has introduced the latest generation of its programmable focusing optics, the PFO 3D, for scanner welding, cutting and drilling. They feature a larger work area, higher maximum laser power and enhanced electronics for increased accuracy.

The maximum work area of the laser has been increased to 20.8 × 30.7 in. in elliptical form with a Z-stroke of up to ±18.7 in. The maximum laser power has been increased to up to 8 kW. To minimize repositioning time and maximize performance in larger applications, a robot-mounted PFO can be controlled to process on the fly through real-time synchronization of the scanner axes and robot axes.

Advancements to the PFO 3D electronics ensure increased accuracy at the workpiece. With the CalibrationLine function, the exact position of the focal point and the power of the laser beam can be determined. The mirror stabilization program corrects mirror positions measured in offset and gain, independent of temperature and humidity.

The “wobble” feature improves materials processing capabilities in bridging gaps, battery welding and creating repeating patterns for a larger contact area with a small focus spot. These changes improve repeatability and enable precise processing results in applications with extremely defined requirements.
